My wife had this done about a yr ago, and she too was bleeding something terrible. And I mean bad!
Now, while it did stop the excessive bleeding, it did not stop the monthly PMS cycle with the cramping, and at times, it seemed worse. She did some reserch on this, and if I remember right, she told me that the lining is scarred over from the ablation, but that the uterus is trying to bleed through the lining and can not get through. I could be way off base here, as this in certianlly not my forte for obvious reasons.
All I know is that your post here sounds just like my wife, in that she is still experiencing PMS cramping pain. She told me last night, she is thinking about getting it all taken out and be done with it.
I certianlly encourge you to visit with your Dr about this. I'm going to let the ladies help you on this one, but just wanted to share what my wife has gone through. Again, I could be way off base here, so do keep checking here for a solid answer.
